In the first incident, a 30-year-old autorickshaw driver Sukhwinder--a resident of Anand Parbat in central Delhi, was hit with an iron rod by his elder brother Dharam Singh, 35, last night.
Sukhwinder was admitted to a hospital where he succumbed to his injury this afternoon, police said.
Both the brothers worked as autorickshaw drivers.
Dharam used to live in Burari and last night he visited his younger brother. They had some dispute during which the accused hit the victim with an iron rod, a senior police officer said, adding Dharam has been arrested.
In another incident, 20-year-old Jane Alam was stabbed multiple times by his elder brother over a petty dispute in Nand Nagri area of east Delhi on Wednesday night.
Jane succumbed due to excessive bleeding while undergoing treatment at GTB hospital last evening.
The victim and his elder brother Shah Alam, 20, had a fight over some issue while they were at their home in Sundar Nagari on July 13, police said.
When their father Mehrajuddin admonished them, they went out of their house and later family members were alarmed by the shrieks and cries of help by the younger sibling, they said.
The stab wounds, confined mostly to the arms and legs of Jane, led to excessive bleeding and he died undergoing treatment at GTB hospital, said the officer.
A case was registered against Shah and now the charge of murder has also been added. He is absconding and efforts are being made to arrest him at the earliest, he added.
